Description

3,5-Dihydroxybenzonitrile is a versatile aromatic nitrile derivative featuring two phenolic hydroxyl groups in a meta-substitution pattern. This unique bifunctional structure makes it a valuable high-purity building block for advanced organic synthesis and pharmaceutical research. It is primarily utilized by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for creating complex molecular architectures.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring a benzonitrile core with phenolic functionality.
• Agrochemical Synthesis: Building block for developing herbicides, fungicides, and plant growth regulators where the nitrile and hydroxyl groups offer sites for further chemical modification.
• Ligand and Chelating Agent Precursor: Used to synthesize polydentate ligands for metal catalysis and coordination chemistry due to its two oxygen donor sites.
• Polymer Chemistry Monomer: Serves as a monomer or co-monomer for producing specialty polymers, such as polyesters or polycarbonates, with enhanced properties.
• Material Science Research: Intermediate in the development of organic electronic materials, dyes, and pigments.
• Chemical Research & Development: A versatile starting material for exploring novel organic reactions and creating compound libraries for screening.

Quality Control

Our 3,5-Dihydroxybenzonitrile is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by IR and NMR spectroscopy, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) detailing all test results are provided with each shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed to minimize exposure to atmospheric humidity.
